Abstract
Channel information is displayed for a user in improved fashion by adjusting the amount of information according to the rate with which the user previews channels. For example, at a first rate of preview, the channel number, channel logo, program name and video could be displayed for each previewed channel, while at a faster rate, the channel number and logo could be displayed, and at a still faster rate the channel number alone could be displayed for each previewed channel. The rate of preview can be dictated by remote control signals, such as those produced by a remote control jog dial. The user can rotate the jog dial to preview channels at various rates and receive corresponding amounts of information for each previewed channel dependent upon the rate that the channels are previewed.
